Leiper's Fork Bottled in Bond Bourbon is one of those bottles that caught my eye specifically because of that "Bottled in Bond" designation on the label. For anyone unfamiliar, Bottled in Bond isn't just marketing — it's a legal standard dating back to the Bottled-in-Bond Act of 1897. It means this bourbon was made at a single distillery, by a single distiller, during a single distilling season, aged at least four years in a federally bonded warehouse, and bottled at exactly 100 proof (50% ABV). That's not a suggestion — it's the law. So when you pick up a BiB bourbon, you're getting a guarantee of transparency that most whiskey labels simply don't offer.
Leiper's Fork takes its name from a small community in Williamson County, Tennessee — real horse country, about thirty miles south of Nashville. The fact that this is a Tennessee Bourbon is worth noting. Tennessee whiskey and bourbon aren't mutually exclusive categories, despite what some people assume. A Tennessee whiskey can absolutely be a bourbon if it meets the legal requirements: made in the US, at least 51% corn mashbill, distilled to no more than 160 proof, entered into new charred oak barrels at no more than 125 proof, and bottled at a minimum of 80 proof. This one ticks every box and then adds the Bottled in Bond standard on top.
At 50% ABV, this sits right at that sweet spot where you're getting serious intensity without the burn becoming the whole conversation. I find that 100 proof bourbons tend to hold up brilliantly in cocktails while still being perfectly drinkable neat — and that dual personality is a big part of what makes the Bottled in Bond category so appealing to me as someone who spent years behind a bar.
The NAS (no age statement) designation means we know it's at least four years old thanks to the BiB rules, but beyond that, Leiper's Fork aren't telling us exactly how long this spent in wood. That's fine by me. Age statements are useful, but they're not the whole story — warehouse placement, barrel selection, and entry proof all play massive roles in how a bourbon develops. What matters is what's in the glass.
Tasting Notes
I'll be honest — I want to let this bourbon speak for itself rather than over-promise on specific notes. What I will say is that at 100 proof from new charred oak, you should expect the kind of bold, full-bodied character that BiB bourbons are known for. Classic bourbon markers — think corn sweetness balanced against oak structure, with the proof giving everything enough backbone to stand up without water.
The Verdict
At £70.95, Leiper's Fork Bottled in Bond sits in a competitive bracket, but I think it justifies its price. You're paying for a bourbon that meets one of the strictest production standards in American whiskey, bottled at a proof that delivers genuine flavour intensity. The BiB designation alone sets it apart from a crowded shelf of NAS bourbons that don't offer the same level of transparency. It's a solid, honest pour — the kind of bottle I'd recommend to someone who wants to understand what Bottled in Bond actually means in practice. A 7.8 out of 10 from me: this is a well-made bourbon that does exactly what it promises, and there's real value in that.
Best Served
This is a natural Old Fashioned bourbon. At 100 proof, it won't get lost under a sugar cube and a few dashes of Angostura — the whiskey stays front and centre. Build it in the glass: one sugar cube, two dashes of aromatic bitters, a splash of water to dissolve, then two ounces of the Leiper's Fork over a large ice cube. Express an orange peel over the top and drop it in. The proof carries the cocktail beautifully. If you prefer it neat, give it five minutes in the glass before your first sip — a little air opens up 100-proof bourbon considerably.
